m f y a'mag-e whee-tensileether pare of t'heinzi'ehine: i The teeth cai'i'iedfbj at at the eu porft ed ina ydbe or drum 41 operated through the mediumof a shaft 42 having the gear 43 at one end 7 meshing with a gear 44 carried. by. the end of the shaft 36 opposite the sprocket 39. This shaft 42 has adjustable longitudinally thereof a friction drive roller 45 adapted to engage the friction disk 46 carried by the cylinder 41 whereby the- -lat;ter is rotated. It is proposed, in the present invention, to

vary the speed of rotation of the cylinder 41 in order to automatically control the distribution of shocks intothe body 13 from the conveyer 37 so that said body will be uniformly loaded and it will be apparent .that'by increasing the speed of the cylinder 41 the shocks; will be thrown toward the rear end of: the body 13 and by decreasing said speed the shockswill fall nearer the front endflof the machine, the distance from vsaid front end decreasing in proportion to the decrease in the speed of rotation of said cylinder; In order to vary this speed of rotation the friction roller 45 is connected to one end of a rod 47 the other end of which is connected to thenbell crank lever 48 car- ,ried by the adjacent side. of the frame .27, V and pivoted to said bell crank lever is a rod or link 49 -to which is connectedthe operating lever 5 0 pivoted to the side of the frame 27 and working over a rack segment 51. It

.willbe seen from this description thatby adjusting the lever 50 the roller 45 may be adjusted toward and away from the center 1 of. the friction disk 46 and thus increase and decrease the speed thereof. Means are also provided for adjusting the conveyer frame 27 toan inoperative position when not 1n use and to this end use is preferably madeof a transverse shaft 52 rotatably supported at the forward end of the body 13 and operated by a hand wheel 53 to wind and unwind the cables or other flexible elements 53 which pass around the pulleys 54 carried bythe body 13 adjacent the upper end thereof, the ends of said cables being secured to the conveyer frame 27 at 55 and it will thus be seen by winding the cables 53 upon the shaft 52 the frame 27 and its associated parts will be slidingly adjusted upon the worm supported by the shaft 61 rotatable in thebearings 62 carried by the frame 10 of the machine. The forward end of the shaft 61 is provided with a gear 63 meshing with a larger gear 64 carried by the shaft 65 journaled transversely of said frame 10 the end of the shaft 65 opposite that carry- Gop ies of this patent may be obtained for k A machine of ing the gear 64 being provided with a sprocket 66 around which passes a drive chain 67 which also engages a sprocket 68 carried upon the adjacent end of the jack shaft 23'so that-assaid shaft is rotated the power will be transmitted through the differe'nt parts just described to therear drum 58 thus operating the apron 56. When loading the body 13 it is desirable that the apron 56 remain stationary and for this purpose the shaft 61 is preferably provided with a clutch69- operable through the medium of a lever 70' pivoted to the frame 10 andarranged adjacent the drivers seat 20.

flVhat is claimed is 1. A machine of the classdescribed comprisinga body, a loadmgconveyer assooiated therewith, a rotatable loading cylinfor varying the speed 'ofirotation of said cylinder whereby to distribute shocks 'into different parts-of said body.

j the classdescribed comprising a body, a loading conveyer associated therewith, a rotatable loading cylinder at .der at oneend of said conveyer, and means one end of said conveyer, a friction} diskv shaft, and a friction drive roller adjustable longitudinally .jsaid shaft and-towardand away from the center of said disk tovary the speed of rotation thereof whereby to distribute shocks into different parts of said body.

4. A machine of the class describedcomtherewith, a rotatable loading cylinder at one end of said conveyer, a friction disk 1 carried by said cylinder, a shaft arranged adjacent thereto, means for driving said shaft, a friction drive roller adjustable longitudinally of said shaft and toward and away from thecenter of said disk to vary the speed of rotation thereof whereby to distribute shocks into different parts of said body, and means supported by said conveyer and connected to said friction roller for adjusting the same. 6 r f In testimony whereof, I aflix my signature in the presence of two witnesses.
